Powassan Virus Cases Surge in Northeastern United States
US · Published Jun 28, 2026
The Powassan virus, a tick-borne illness first identified in 1958, is being diagnosed more frequently in the northeastern United States.
In 2025, 76 cases were reported, marking a record high.

Impact & Risks

The Powassan virus poses significant health risks, particularly in New England and the Upper Midwest, where most cases have been reported. The virus can cause severe neurological complications and has a high fatality rate for symptomatic cases. Vulnerable populations, including outdoor enthusiasts and those in tick-prone areas, are at greater risk. The rapid transmission of the virus, which can occur in under 15 minutes after a tick bite, makes early detection and prevention critical.
